I'm now reminded of a line that I mis-read and wanted to make into a story, but never got it to work.
I had read "I need your help to flesh and expand this," as "I need your help and flesh to expand this."
I now don't have to finish writing that story because god dammit this is better.

Also, there's a problem that it isn't just one organism, but a collection of otherwise mundane bacteria and virus. Containing this requires containing all its components, or preventing them from ganging up in the wild, and we don't know how to do that. And because its initial stage is asymptomatic, SCP-1801-1 could be passing on the pieces-parts without suffering fatal symptoms until it passed on full blown SCP-1801. So SCP-1801-1 might not casually give you SCP-1801-1, but could pass on something like Ebola or Pneumonic Plague.
